FEED-WATER PURIFIER.

Specification of Letters Patent. *Y Patented Allg. 31, 1909.

' Application filed. January 4, 1909.. Serial No. 470,577.

To all whom it may concern:

Be it known that I,JoiiN Woon, Jr., citizen of the `United States, vresidingfat Conshohocken, county of Montgomery, and State of Pennsylvania, have invented certain new and useful Improvements in F eed-Water Purifiers, of which the "following is a specificatiomreference being had therein to thev accompanying drawing.

This invention relates to a feed `water purifier, and particularly to a structure whereby the liquid is superheated or vaporized andthe sediment collected therefrom before its introduction into thel steam boiler so as to remove'tlie scale forming material from the water.

The invention has for an object to provide a casing formed with a feed chamber at its upper portion and a sediment chamber at the lower portion thereof and a steam` chamber with discharge openings intermediate of said portions in connection with superlieating pipes whereby the liquid may be superheated vor vaporized in its passage to the casing. l Y

A further object of theV invention is to provide the portion of the casing intermediate of the feed and sediment chambers with baflie plates extending longitudinally beneath the discharge openings in order to prevent sediment being carried through said openings in the feeding flow to the boiler, and also transversely disposed partitions above the sedimentchamber in order that the cleaning of this chamber by thev` blowing olf action may notbe confined to any particular part thereof,y and thel lower portion of the casing divided into a` series of independently acting sections. a

Other and further objects and advantages of the invention will be hereinafter fully set forth andthe novel'features thereof defined by the appended claims. i

In the drawing Figure 1 is a vertical section through a steam boiler showing the application of the invention thereto. Fig. 2 is an elevation of the purifying casing with portion thereof in vertical. section;

Fig. 3 is a transverse vertical section through Fig. 2; Fig. 4 is a plan of the casing and its connections. i

Like numerals refer to like part-s in the several views of the drawing.

The numeral 10 designates a steam boiler which may be of any desired construction or configuration asV the invention is applicable to any and all forms of heating apparatus to which 4water is fed. The purifier casing 11 is disposedwithin the boiler in any desired position with the upper portion thereof above the water level and in the steam space of the boiler. This casing may be formed in any desired shape or manner and is here shown as comprising separate sections centrally joined by means of the bolting iiange 12, while the opposite ends of these sections are each formed with threaded openings 13 and 1-L for the application ofthe pipe connections and so as to permit their-*reversal in position whenever desired, The opening 13 at one end is adapted to receive a feed pipe 15 at the upper portion, while the opening 14 at the opposite end is adapted to receive :the blow off pipe 16 Vat the lower portion. l The remaining openings 13 and 14 are closed z by means ofplugs 17 in the usual manner.

In the form of casing here shown the Iupper portion is formed as a circular feed chamber leV having at its lower portion a longitudinally extending slot or opening 19 of less diameter or area than the chamber. The lower portion of the casing is formed with a similarly shaped sediment chamber 20 also having a longitudinally extending opening 21 of lessdiameter than the chamber. Intermediate of these chambers the casing is enlarged as shownat 22 and the walls thereof provided with discharge openings '23. Beneath these openings and extending longitudinally ofthe casing are ballie plates 24 disposed at substantially right an` gles to the natural flow through these openings and arranged to prevent the sediment or solid matter being carried with the feed water throughthe discharge openings. EX- tending transversely of the casing are a scries of partitionsv25 each formed adjacent the opening 21 with a cutaway portion 26. These partitions divide the casing into a series of sections acting independently so that in the cleaning or blowing olf action no material can collect in any portion of the sediment chamber as the pressure is applied equally to all parts of the casing. Y

, In order to secure. the most etlicient precipitation of the sediment or solidniatters it is desirable to superheattlie waterbefore its entrance into the feed chamber and this may be effected by any preferred arrangement of vaporizing or superlieating pipes, for instance, a return coil 27 which may be formed with any required length of pipes and disposed in any desired position relative to the casing, but preferably above the water level and in the steam space of the boiler. This superheating pipeis connected to the usual water feed. The opposite end of the casing is, also connected with the'usual blow off 28 by Ameans oftheV pipe connection 2,9

' provided with the controlling valve 30 which when opened permits the boiler pressureto act through the purifier casing and force the collected sediment from the lower chambei' thereof.

In the operation of the invention the feed water is superheatedv or vaporized and the solid or scale forming materials are thus precipitated as the water is discharged from the feed chamber into the body of the casing. These lsolid matters pass downward into the sediment chamber and into the lower portion thereof, while the purified water is diseharged through the openings at the opposite sides of the casing which are preferably disposed about the normal water level of the boiler. The discharge'through the contracted opening at the lower portion of the chamber causes'the water to pass through the steam space within the easing intermediate the two chambers, and the water having been'previously brought to a high temperature in the superheating pipe is thus raised to point of vaporization. This having taken place the solid matters are precipitated 'by' gravity to the sediment chamber which is connected to the casing by the slot opening extending for thelength thereof. Whenever it is desired to clean or discharge the sediment chamber the valve in the blow off pipe may be opened and the accumulated solid matters drawn 0H. The arrangement of the baffle plates beneath the discharge openings from the steam space prevents any sediment being carried to the boiler in the flow of the feed water, while the division ofV the casing into sections by the transverse partitions equalizes the blowing off action and applies the pressure to each and all parts of the sediment chamber. It will therefore 'be seen that'this invention presents, a simple, efficient and economically constructedY form of water purifier adapted forapplication` to all forms of boilers already Vin useand in its feeding action eectually removes all sediment and solid mattei' lfrom the feed water thus preventing the formation of scale upon the walls of the boiler or the` tubes thereof.

' Having described my invention and set i forth its'merits, what I claim and desire to secure by Letters Patent is l.
